Antialiasing methods for laser printers
Font and graphics antialiasing are often used methods of enhancing the output quality of video monitors. The same techniques also can enhance the quality of laser printer output. Since the laser printing process and the monitor display process differ radically, the assumptions made for antialiasing …

Estimating toner usage with laser electrophotographic printers, and object map generation from raster input image
… importance for laser, electrophotographic (EP) printers. In Part 1, we propose a new two-stage approach in which we first predict on a pixel-by-pixel basis, the absorptance from printed and scanned pages. We then form a weighted sum of these pixel values to predict overall toner usage on the …

Analysis of the Effects of Basic Printer Settings on PLA 3D Prints
Desktop-size 3D printers are capable of producing functional prints for an extremely wide variety of designs, but many hobbyist printers still struggle with print defects such as warping, stringing, and blobbing appearing on their prints. There are many existing recommendations for dealing with any …
